Flat valve seat

The valve seat structure for flat valves includes a valve body, a gate plate, a wave spring, an O-ring, and a valve seat. The gate is connected to the valve seat, and the valve seat is connected to the valve body. One end of the valve seat connected to the valve body has a protrusion, and an O-ring is installed in the middle of the protrusion. A circular groove is formed at the connection between the valve seat and the valve body, and a wave spring is installed inside the groove. Compared with existing technologies, this new type of flat valve seat has more stable performance and is easy to disassemble and assemble.
